Rick rents a car from a company that charges him $25 per day plus 10 cents per mile driven. Which expression can represent the amount he owed on a recent rental?a.) 25x + 0.1y
b.) 251.x
c.) 25.1xy
d.) 25.1 + 35y

Answers

Answer 1
Answer: Let x be the number of days and y represent miles driven.

Since it costs 25 per day, you multiply 25 by x.
25x

10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y

25x+.1y

The answer is a.) 25x + 0.1y.

The graph of an inequality has an open circle at 3.9, and the ray moves to the right. What inequality is graphed?

Answers

Answer:

The required inequality is x > 3.9

Step-by-step explanation:

Consider the provided information.

The closed circle means that the set contain that extreme.

For closed circle we use the inequality "≤" or "≥"

The open circle means that the set does not contain that extreme.

For open circle we use the inequality "<" or ">"  

Here, it is given that the graph has an open circle, therefore the required inequality should be "<" or ">"

If the ray moves right, in the usual notation, the real numbers increase to the right, if it moves to left the real numbers decreases.

It is given that the ray moves to right that means the set of numbers bigger than 3.9, that does not contain the number 3.9

Hence, the required inequality is x > 3.9

Where x is any number greater than 3.9.

The answer would be x > 3.9

Sadie weights out 690 grams of flour. Using the rate from Q4, how many cups did she weigh?

Answers

The Sadie weights out 690 grams of flour the rate from Q4 5.75 cups of flour.

To convert the weight of flour from grams to cups, to know the conversion rate between grams and cups for flour. The conversion rate can vary depending on the density and type of flour being used.

Assuming the conversion rate provided in Q4 is for the specific type of flour Sadie is using,  use the rate to find the number of cups.

Let's assume the rate given in Q4 is: 120 grams of flour = 1 cup of flour.

Now, we can calculate the number of cups of flour Sadie weighed:

Number of cups = Weight of flour in grams / Conversion rate

Number of cups = 690 grams / 120 grams per cup

Number of cups ≈ 5.75 cups

Verify the Pythagorean Identity 1 + cos^2(theta) = csc^2(theta)

Answers

1 + cot² t = csc² t
1+cot ^(2) t = (1)/(sin ^(2) t) \n 1+ (cos^(2)t )/(sin^(2)t ) = (1)/(sin ^(2) t)  / * sin² t
sin² t + cos² t = 1
1 = 1
We have confirmed the identity.

The verification for the Pythagorean identity 1 + cot²∅ = cosec²∅ will lead to  sin²∅ + cos²∅ = 1

How to verify Pythagorean identity?

1 + cot²∅ = cosec²∅

Therefore,

cosec²∅ = 1 / sin²∅

cot²∅ = 1 / tan²∅ = cos²∅ / sin²∅

Hence,

1 + cos²∅ / sin²∅ =  1 / sin²∅

Therefore, multiply both sides by sin²∅

1(sin²∅) + (sin²∅) cos²∅ / sin²∅ = (sin²∅) 1 / sin²∅

sin²∅ + cos²∅ = 1

Answers

The probability that Rob will randomly select a green t-shirt, given that he has 6 green and 15 of other colors, is 2/7.

Answer:

2/7

Step-by-step explanation:

P (probability) = number of successful events / number of all events

P = 6 / (6+15) = 6 / 21 = 2 / 7
